When your body
thinks you're dying.

What's actually happening in your body

Let's start with what almost nobody explains, and it changes your whole relationship with this: nothing has broken. What you have is an alarm system working perfectly — that has gone off at the wrong moment.

Your body comes with a mechanism to save you from real danger — a car coming at you, an animal, a fall. When it fires, it does all of this at once: it releases adrenaline; it speeds up your heart to send blood to your muscles; it makes you breathe fast to take in more oxygen; it pulls blood away from your hands and feet (which is exactly why they tingle, and why they go cold); it dilates your pupils; it makes you sweat to cool you down.

Read that again and compare it with what you feel. It's all there. Item by item. What happens to you isn't an inexplicable disaster: it's a survival kit deploying in full. The problem isn't that it works badly. It's that it fired with no lion anywhere.

Why it feels like a heart attack (and why it isn't)

Almost everything else is explained by one thing: your breathing. When you're frightened, you breathe faster than you need to. Doing that blows off more carbon dioxide than you produce, and that imbalance — which isn't dangerous — produces precisely the symptoms that scare you most: dizziness, tingling, strange vision, a sense of unreality, tightness in the chest, the feeling that air isn't getting in. Notice the irony: you feel short of oxygen when in fact you have too much.

And there are four things worth knowing, because they're true and because panic feeds on believing the opposite:

A panic attack won't kill you. However fierce the racing heart, it's the same rate you'd have running up stairs. Your heart is built for that.

You're not going to faint. This surprises everyone: fainting happens when blood pressure drops, and in panic your blood pressure rises. You feel like you'll collapse, and it's precisely the thing that won't happen.

You're not going mad. That sense of unreality — of being outside yourself, of the world being a stage set — has a name and is a well-known symptom of high anxiety. It isn't the beginning of anything worse. It passes when the alarm comes down.

And the peak is short. Minutes. Your body can't sustain a surge like that for long: it runs out of fuel. The wave rises, crests and falls. Always. Without exception. Even if you do absolutely nothing.

What to do while it lasts

Name it. Out loud or inside: "this is a panic attack. It's a false alarm. It will rise, it will peak, and it will come down." Naming it isn't a self-help trick: it's what stops your mind from reading every heartbeat as proof that you're dying — and that reading is panic's fuel.

Let the air out, don't grab for it. Instinct tells you to breathe deep and fast, and that makes it worse. Do the opposite: take air slowly through your nose for a count of four, and let it out long, for a count of six or eight. The slow out-breath is what puts a foot on the body's brake. It doesn't have to be perfect; it just has to let out more than you take in.

Stay. This is the hard one and the one that matters most. Every part of you will want to run out of the supermarket, the car, the meeting. If you go, you'll feel immediate relief — and you'll have taught your brain that the place really was dangerous and that you only survived because you fled. That's how the world starts to shrink.

And don't fight it. That sounds contradictory after the last point, but it isn't: staying doesn't mean fighting. Fighting panic — bracing, tensing, trying to stop it — feeds it, because tensing is exactly what your body does when there's danger. What works is the hardest thing of all: letting it pass. Sit down, if you can. Put your feet on the floor and feel them. And wait, the way you'd wait for rain to stop.

What quietly makes it worse

Here's the part almost nobody tells you, and it's what turns a bad moment into a lasting problem.

Avoiding. You stop going to the supermarket where it happened. Then to similar places. Then the underground, just in case. Each avoidance relieves you today and shrinks your life tomorrow. That's how agoraphobia begins — not all at once: through perfectly reasonable decisions.

Talismans. The pill in your pocket you never take. The bottle of water. Only going out if someone comes with you. They look like help, and they do something worse than not helping: they keep alive the idea that you survived because you had them. And while that idea stands, the fear stands.

Monitoring yourself. Spending the day listening to your heart, checking whether you're breathing properly, taking your pulse. If you look for signs of danger in your body, you'll find them — everyone has skipped beats, dizziness and tightness. And every finding sets the alarm off again.

Going back to A&E. The first time you should go, and I said so at the top. But once the physical has been ruled out, each new visit teaches your brain that it really was an emergency. The relief of being told "it's nothing" lasts hours; the lesson your fear learns lasts months.

The fear of the fear

And so we reach the mechanism that explains all of it. After the first attack, something new appears: the fear that it will come back. And that fear leaves you on guard, listening, measuring yourself. And being on guard is precisely the state that makes the next attack more likely.

So the problem stops being the attack. The problem becomes the fear of the attack — and that's where the work is. It's a perfect trap, and it has a way out: panic is one of the problems that responds best to psychological treatment. That isn't a consoling phrase; it's one of the things we know how to do well.

When to ask for help

Ask if it has happened more than once. If you've started avoiding places, even one. If you live waiting for it to return. If you're organising your life around something that lasts eight minutes.

You don't have to wait until it's worse. A single panic attack happens to plenty of people and never returns; but once the fear of the fear settles in, the sooner it's treated, the less world you lose along the way. Here's how to find a psychologist without getting lost, and if this lives alongside a background anxiety that won't switch off or a head that won't stop at night, both are looked at closely — as is the anxiety that won't go quiet. And if the weight is heavier than usual today, there's a hand available right now.

If you take one thing from this: you're not dying. Your body set off an alarm that wasn't needed, with all the equipment it comes with. And alarms, once you learn not to run, eventually stop ringing.
